The most successful businesses are those with confidence in their ability to store, access and use data effectively. Rather than focusing on the nuts and bolts of storage, this view point looks at the data it holds and more importantly, what can be done with it.

This review looks at why small businesses need to stop being complacent about their networks and at what they can do to maintain their competitive edge as they follow the big boys down the route of increasing collaboration and other bandwidth-hungry applications likely to impact on network performance and availability.

"This campaign, working undetected since 2011, targets senior US military and diplomatic personnel, congressional personnel, Washington DC area journalists, US think tanks, defence contractors in the US and Israel, as well as others who are vocal supporters of Israel to covertly obtain log-in credentials to the email systems of their victims," read the report.

The attacks targeted people with requests from fake online personas claiming to work in journalism, government and defence contracting.

"These credible personas connected, linked, followed and 'friended' target victims, giving them access to information on location, activities and relationships from updates and other common content," explained iSight.

"Accounts were then targeted with 'spear-phishing' messages. Links which appeared to be legitimate asked recipients to log-in to false pages, thus capturing credential information."

The security firm said it is currently unclear what data was taken during the attacks.

"We are unable to say with complete visibility. However, it is reasonable to assume that a vast amount of social content was compromised in addition to some number of log-in credentials that can be used to access additional systems and information," read the report.

"As users often maintain the same credentials for multiple sites, it is impossible to determine the scope, scale and duration of data loss."
